Grade 5 Operations - 5.OAT.1
What is PEMDAS? The acronym PEMDAS stands for parentheses, exponents, multiplication, division, addition, and subtraction. When you are given two or more operations in a problem, PEMDAS tells us about the order of solving the problem. It tells you what to calculate first, second and so on to the completion of the problem. If a problem has a grouping of symbols, PEMDAS tells which mathematical symbol to calculate first. Without PEMDAS, obtaining one correct answer would be difficult. For example, if we are given an expression 2 x 4 + 7. We could multiply first and get the answer 15. However, if we add first and then multiply, then we will get 22. Which is the correct answer? PEMDAS resolves this confusion. Applying PEMDAS to the example, we will get 15. The order of solution is multiplication first and then addition. Here is how PEMDAS works: P that is parentheses means that you solve for the grouping symbols first. Second, E, which is exponents. Take numbers with exponents and solve them for their respective powers. In PEMDAS, M for multiplication and D for division have the same priority. Complete these two mathematical operations in the order from left to right. Similar to multiplication and division, A for addition and S or subtraction also have the same priority. Look for these two operations from left to right and calculate them in order. These worksheets and lessons have students apply PEMDAS to problems.
